Rubber products are made of rubber raw materials for the mixing machine after the mixing of rubber as raw materials, according to the characteristics of rubber products required in the mixing of the design formula, and set the required product hardness. The product is molded by rubber plate vulcanizing machine. After the product molding, the final edge treatment, the product surface treatment is smooth without burr.

Products Materials

Material	NBR(Nitrile Rubber ( Buna ))
Advantage	1.Excellent oil resistance 2.Hydrolytic resistance 3.Excellent wear resistance 4.Good air tightness 5.Excellent antistatic properties 6.Resistant to alcohol
Disadvantage	1.Poor cold resistance 2.Not resistant to ozone
Temperature	54℃~135℃
Application	NBR is mainly used to manufacture oil resistant rubber products

NBR is mainly used to manufacture oil resistant rubber products. Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better oil resistance, but cold resistance is decreased. It can be used in 120℃ air or 150℃ oil for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used to produce all kinds of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushing, flexible packaging, flexible hose, printing and dyeing roller, cable adhesive materials, etc. It has become an indispensable elastic material in automobile, aviation, petroleum, photocopying and other industries.
